Plant Protection Products are biologically active and potentially toxic preparations, which are regulated under a series of laws and ordinances in Switzerland. In order to protect man and environment against harmful effects of pesticides, market control measures are in force to support the regulations. Whereas several Federal Government authorities are responsible for registration, the market control is primarily in the hand of the Cantons. This calls for a coordinated process of authorities both from the side of the Federal Government and Cantons for monitoring the compliance of pesticides on the market with the details of registration. We report on the first integrated market survey of pesticides with isoproturon on the Swiss Market aiming at all relevant aspects of packaging, labelling, as well as the chemical and physical quality of the pesticides.
Symbiotic nitrogen fixation by bacteria in the soil coexisting with legumes leads to reduced fertiliser requirement. It is not easy to measure this variable on farms, however. Now researchers from Agroscope have developed a method for estimating nitrogen input via symbiotic fixation at farm level.
With increasing global and regional temperatures, even in Switzerland the growing season has lengthened considerably. Using data from the Federal Office of Meteorology and Climatology, Agroscope has traced the development of the growing season since the start of the previous century.
The phosphate mineral reserves required for fertiliser production could be exhausted on a global scale in just a few decades. This study presents a method for recycling a Swiss industrial by-product into a phosphate fertiliser.
